Timber structures - Structural timber and glued laminated timber - Determination of some physical and mechanical properties

This European Standard specifies test methods for determining the following properties of structural timber and glued laminated timber: modulus of elasticity in bending; shear modulus; bending strength; modulus of elasticity in tension parallel to the grain; tension strength parallel to the grain; modulus of elasticity in compression parallel to the grain; compression strength parallel to the grain; modulus of elasticity in tension perpendicular to the grain; tension strength perpendicular to the grain; modulus of elasticity in compression perpendicular to the grain; compression strength perpendicular to the grain and shear strength.
In addition, the determination of dimensions, moisture content, and density of test pieces are specified.
The methods apply to rectangular and circular shapes (of substantially constant cross section) of solid unjointed timber or finger-jointed timber and glued laminated timber unless stated otherwise.

Holzbauwerke - Bauholz für tragende Zwecke und Brettschichtholz - Bestimmung einiger physikalischer und mechanischer Eigenschaften

Diese Europäische Norm legt Prüfverfahren zur Bestimmung der folgenden Eigenschaften von Bauholz für tragende Zwecke und Brettschichtholz fest: Biege-Elastizitätsmodul, Schubmodul, Biegefestigkeit, Zug-Elasti-zitätsmodul in Faserrichtung, Zugfestigkeit in Faserrichtung, Druck-Elastizitätsmodul in Faserrichtung, Druck-festigkeit in Faserrichtung, Zug-Elastizitätsmodul rechtwinklig zur Faserrichtung, Zugfestigkeit rechtwinklig zur Faserrichtung, Druck-Elastizitätsmodul rechtwinklig zur Faserrichtung, Druckfestigkeit rechtwinklig zur Faser-richtung sowie die Scherfestigkeit. Zusätzlich wird die Bestimmung der Maße, der Holzfeuchte und der Rohdichte festgelegt. Sofern nicht anders angegeben, gelten die Verfahren für rechteckige und kreisförmige Formen (mit im Wesentlichen konstantem Querschnitt) aus ungestoßenem oder keilgezinktem Bauholz und Brettschichtholz.

Structures en bois - Bois de structure et bois lamellé-collé - Détermination de certaines propriétés physiques et mécaniques

La présente Norme européenne définit des méthodes d'essai pour déterminer les propriétés suivantes du bois
de structure et du bois lamellé-collé : le module d'élasticité en flexion, le module de cisaillement, la résistance
à la flexion, le module d'élasticité en traction axiale, la résistance à la traction axiale, le module d'élasticité en
compression axiale, la résistance à la compression axiale, le module d'élasticité en traction transversale, la
résistance à la traction transversale, le module d'élasticité en compression transversale, la résistance à la
compression transversale et la résistance au cisaillement.
La détermination des dimensions, de la teneur en humidité et de la masse volumique des éprouvettes d'essai
est également définie.
Sauf indication contraire, les méthodes s'appliquent aux bois massifs non aboutés ou aboutés par entures
multiples et aux bois lamellés-collés, de formes rectangulaire et circulaire (de section relativement constante).

Lesene konstrukcije - Konstrukcijski les in lepljeni lamelirani les - Ugotavljanje nekaterih fizikalnih in mehanskih lastnosti

Ta evropski standard določa preskusne metode za ugotavljanje naslednjih lastnosti strukturnega lesa in lameliranega lepljenega lesa: modul elastičnosti upogibanja; strižni modul; moč upogibanja; modul elastičnosti pri napetosti, vzporedni z vlakni; modul elastičnosti pri moči stiskanja, vzporedni z vlakni; modul elastičnosti pri napetosti navpično na vlakna; moč stiskanja navpično na vlakna; modul elastičnosti pri stiskanju navpično na vlakna; moč stiskanja navpično na vlakna in moč striženja. Poleg tega je opredeljeno določevanje dimenzij, vlage in gostote preskušancev. Metode veljajo za pravokotne in okrogle oblike (konstantnega prereza) trdnega nespajanega lesa ali lesa, spajanega z zobatimi spoji, ter lameliranega lepljenega lesa, razen če je navedeno drugače.
